7 Claims.

My invention relates to improvements in rotary photograph printing machines, and has for an object to. provide a machine for printing photographs which may be driven at desired constant speeds and into which sheets of photographic printing paper may be fed for exposure for definite periods of time to light when in the machine contacting with photographic negatives therein and which subsequently may fall from the machine into a developing bath.

Another object of my improvement is to provide a photographic printing machine which will eX- pose the sensitized paper for equal periods of time.

Another object of my improvement is to provide for photographic machine printing more rapidly than'is possible when making the exposures by hand.

Another object of my improvement is to design a photographic printer having few and simple parts not expensive to make nor likely to get out of order. 4

Other objects of my invention will appear as the description proceeds.

I attain these andother objects of my invention with the mechanism illustrated in the accompanying two sheets of drawings, forming a part of this specification, in which Figure 1 is a top plan view of my rotary photographic printing machine, Fig. 2 is a sectional View of a part of Fig. l on the line 2-2 revolved downward through an angle of 45, Fig. 3 is a front elevation of the lamp supporting bracket a part of which is broken away, Fig. 4 is a front side elevation of Fig. 1, Fig. 5 is a plan view of the double hinge used in the machine drawn on a larger scale shown by itself, and Fig. 6 is an edge elevation of Fig. 5.

Similar characters refer to similar parts throughout.

Certain parts are broken away to show other parts hidden thereby.

With more particular reference to designated parts: On a base l is fastened the bearing bracket 8 which mounts the shaft I0 for revolution. One end of the shaft l0 is centrally disposed i-n the closed endga of the hollow cylinder 9 and fastened therein. The construction provides for the revolution of the cylinder 9 on the bearing l0.

On the iront end of the base is fastened the front base wall la, and to this wall are fastened two similar bearing brackets 28, 28 which mount the shaft 29a for revolution, disposed parallel with the elements of cylinder 9, laterally beneath the cylinder. The roller v29 is centrally mounted on the shaft 29a and fastened thereon to yrevolve therewith. Two bearing brackets x3l), only one of Vto the housing and to the base l.

which is shown, are fastened on the base l and mount the shaft 3|a for revolution disposed parallel with the elements of the cylinder 9 and beneath the center thereof. The roller 3| is mounted on the shaft 3N and fastened thereon to revolve therewith. Two brackets 35, 35 are fastened on the base l beneath the cylinder 9 and to the inclined tcp of each is adjustably clamped a similar bearing arm 32 by the clamping bolts 3ft, S4 extended through the slot 33. The shaft 37a is mounted in the bearing arms 32 for revolution parallel with the elements of the cylinder 9 and with the shafts 29a and Sla. On the shaft 3la is `mounted the roller 3l fastened thereon to revolve therewith.

Over the rollers 29, 3! and 3l is placed the webbing endless belt Sli and adjusted closely beneath and against the lower part of the cylinder 9 by means of the longitudinally adjustable bearing arms 32. Fastened on the rear end of the roller shaft 2921 is the pulley Si and handle crank 68, and the cylinder 9 may be revolved in the direction indicated by the arrow in Fig. 4 by a power belt, not shown, over the pulley 6l or by hand on the crank E8. There are four, spaced, rectangular openings, Il, l2. i3 and lll in the peripheral walls of the cylinder 9, and in theml are placed the segmental glass windows i5, H5, il and i8, respectively and cemented securely therein. Over each of the glass windows is placed a photographic negative, i9, and fastened in place. In practice, pieces of adhesive tape, shown at 20, serve very well to retain the negatives in place on the windows.

An electric lamp bulb housing 22 is retained in transverse and horizontal central position within the cylinder S by the angular bracket 2l fastened The housing 22 is open at the bottom end only and thereat has the downwardly and inwardly inclined baiile plates 27, v'.l to limit the beam of light which may pass therethrough from the lamp 23 mounted in Ythe housing and connected with a service electric circuit by the wires V26.

All oi the walls of the lamp housing are closely joined and opaque except the top wall 25, which is made of frosted glass, and in the front wall is set the red lens 2a. The frosted glass provides a weak `light beneath the glass window at the top to aid in correctly placing a negative thereover, and the red lens provides non-actinic illumination for the dark room in which the printer is used.

Four similar feed arms are pivoted at equal spaces on the edge of the open end of the cylinder 9. Each of the feed arms consists of the adjustable shank 38, 49 clamped together by the coupling 59, the hook 4l, the nib 42 on the hook end extended at right angles therewith, and the handle 39 at an angle with the shank. The handle, shank and hook are, substantially, in the same plane while the nib is at right angles with this plane.

The double hinge 44, 41 has the hinge pins 45 and 49 at right angles with each other and, substantially, in the same plane. On one of the leaves of the hinge 44 is the longitudinal boss 43 with the hole 43a lengthwise therethrough. The handle 39 is extended through this hole and fastened therein with its free end protruding beyond the hinge end. In each hinge, 44 and 41,

, the hinge eyes are preferably vof an even number and the hinge pin extends at one end beyond the end of the hinge and mounts one of the coil springs 49, or 45 thereon to react between the pin head and the outer hinge eye at that end of the hinge on one leaf While the other pin head bears on the outer hinge eye on the other leaf, thus adjacent hing-e eyes are forced against each other with irictional pressure by the spring reaction which provides resistance against hinge operations.

The outer leaf of hinge 41 is fastened on the interior of the cylinder wall with its hinge pin 48 parallel with the cylinder elements, the spring 49 within the cylinder, and an end of the hinge protruding outside of the cylinder Wall edge. This Y disposition of the part 4'! of the double hinge places the part 44 thereof entirely outside of the cylinder 9, as shown in Fig. l. The disposition of the feed arms, when not in operation or being oscillated, is shown in Figs. 1 and 4 with respect to the arms shown at the top, bottom and left-hand side of the cylinder. The resistance to hinge operation caused by the springs 46 and 49, by construction, is suiiicient to retain the arms in such positions as they may be at the conclusion of their operative movements.

A tipping and guide rod is bent to provide a handle 52, a standard 53 at right angles with the handle, an inclined lateral 53SL at an angle with the standard, and the tipping arm 54 parallel with the handle 52; The handle 52 is extended into a hole in the bracket l and fastened therein. The bracket 5l is fastened to the base Wall 1a to dispose the handle 52 horizontally and the standard 53 extending upwardly and outwardly and the arm 54 horizontal with its free end outside of `and adjacent the plane of the open end of the cylinder 9. The parts 53 and 53aL serve as guides and incline away from the end of the cylinder, as shown in Fig. l.-

Two parallel sensitized-paper guides 55, 55 are mounted on the base wall 1a and fastened theref on by the angle brackets 56, 56 and disposed with their plane at an inclination of about 45 with the horizon inclined downward toward the cylin der 9 with their lower ends adjacent the cylinder and the roller 29 and the belt 39 thereover. The upper and outer ends of guides 55 are spaced by the crossbar 51 fastened to the bottoms thereof. Onv the top wall of the front guide 55 near its lower end is fastened the upward-incline elevator guide B9. Between the guide 66 and the lower end of the said guide 55 on top of the said guide 55 is fastened the angle-bar guide 65 with its ends projected beyond the said guide 55 and its outer end nearer the lower end of the guide 55 than is its upper end; that is, it is in a plane pare alle] with and above the plane of the guides 55,

edge at the dotted line at A in Fig. 1.

55 and inclined with respect to these guides. A slot opening 58 is made in the rear wall of the rear guide 55 and the lugs 59 and 60 extend rearwardly from the said rear wall, one at each end of the slot. The shoe 6| is extended through the slot 58 into the guide slot of the rear guide 55 and its rearwardly projected arm 63 is pivoted to the lug 59 for oscillation in the guide slot. The stop Sla on the free end of the shoe 6I bears on the outer wall of the guide 55 when the shoe is at its maximum position within the guide slot. The spring 94 is stretched between the shoe arm 63 and the lug 99 to react and tend to retain the shoe within the guide slot. A light pressure outward against the inner edge of the shoe 6| will move the shoe to its outward position, shown Y in dotted lines at 9| against the reaction of the spring 64.

In operation: It is assumed that the roller 29 is being revolved in a counter-clockwise direction, driving the cradle belt 39 and revolving the cylinder 9 in a clockwise direction. A piece of sensitized photographic paper of dimensions suitable for printing from the negatives I9 is inserted iiatwise in the guides 55 with its upper The revolving cylinder will cause the outer end of the handle 39, on one of the feed arms, to bear on the tipping arm 54 and oscillate the said feed arm on a hinge pin 48 till it is disposed in the position shown in dotted outlines in Fig. 4 when the handle 39 thereof may pass the tipping arm. At this time the feed arm handle is at 39', the outer hinge pin at 45', the inner hinge pin at 48', the attached hinge leaf at 41', the shank at 38' and the hook nib at 42. Continued revolution of the cylinder 9 will cause the hook 4I to bear on the front guide 55 near the upper end thereof and as the said hook moves downward on the guide, under the pull of the revolving cylinder, the nib 42 will bear on the upper edge A of the said photographic paper and push the same downward in the guides 55 till the top edge of the paper reaches its dotted position at A when the lower edge of the said paper will have been caught between the cylinder 9 and the belt 35 at the junction thereof and thereafter will be drawn further in between the cylinder and belt and the feeding pressure from the nib 42 is no longer required. However, the movement of thesaid nib and the periphery of the cylinder are so nearly the same that continued contact of the nib on the paper edge as both are drawn downward will not injure the paper.

The said feed arm hook continues moving Vdownward while bearing on top of the said guide 55, being drawn by the revolving cylinder 9, till it reaches the upper end of the inclined elevator guide 66 when it is raised above the guide 55 as it passes along the top of the inclined guide, till on reaching the lower end of the guide 69, which is relatively the highest part of the said guide, the hook nibr42 is above the bottom flange of the angle-bar guide 95 and the hook 4l drops from the guide 69 and falls till the nib 42 bears on the said bottom flange of the angle bar 65. As the hook proceeds downward it bears against the standing flange of the guide 65 and is drawn laterally by this inclined flange till when it passes the outer end thereof the nib end of the hook 4l is in front of the front end of cylinder 9 with a space therebetween, as shown in Fig. l.

By construction, the piece of sensitized paper fed into the printer between the cylinder and belt bythe feed arm, as described, will make desired 'aooasve `register with the negative I9 which is shown in Fig'. l as being on the glass IS'; and, as the belt and cylinder continue to move with the 'sensitized paper therebetween, in due course it will pass beheath the lamp 23 light from which will pass through the glass and the uncolored areas of the negative and produce the results expected in such cases and print the paper which continues betiveen the negative and belt till it is dropped over the turn in the belt, when passing over the roller 37, into the developing bath.

Meanwhile, the next feed arm in order has gone through with the same movements asdescribed above and pushed another piece of sensitized paper between the belt 36 and the negative on the glass l5, which has passed beneath the lamp 23 and has been printed as above described.

If the belt 36 be power driven, the operator need only place pieces of the sensitized paper into the upper ends of the guides 55 and move them downward, one at a time, till the upper edge thereof is within reach of the next descending hook nib.

During the oscillation of the feed arm which occurs while the feed arm handle and the tipping arm are engaged, the shank 33, 49 of the feed arm contacts with the guides 53 and 53a and the feed arm is turned thereby on the hinge pin 45 from its position where the nib 42 is in front of the cylinder 9 to its position where the said nib is between the guide bars 55, as shown in Fig. 1.

During the passage of the pieces 'of sensitized paper in the guides 55 they are moved transversely by the shoe 6| to bear against the front one of the guides 55. The paper thus is aligned with this guide in cases where there is a slight difference in the width thereof.
